A device has a chain fitting which is connected to the floor of a transportation vehicle, such as a flatbed trailer. The chain fitting has a cap on one end thereof, which is installed in a mating aperture formed in the vehicle floor. The side rail has an aperture opposite the floor aperture, this aperture having a smaller diameter than the floor aperture. A side rail is installed along an edge of the floor, tis side rail having an aperture positioned opposite the aperture in the floor and having a smaller diameter than the floor aperture. The cap is installed on the top side of the floor with a short chain piece attached thereto running through the aperture with a second cap at the lower end which is secured to the lower end of the chain. A length of securing chain is attached to the chain fitting, this securing chain being attached to cargo to be restrained. The cap is partially beveled along its contact surface with the floor and engages the sides of the aperture in the floor. This beveled portion operating in conjunction with the aperture sides enables ready release of the cap with one's fingers.

I claim: 1. A device in form of a chain fitting for firmly holding a support chain to a floor of a vehicle, said floor having a floor aperture formed therein, a rail structure including a bracket and attached to the floor, said rail structure having a bracket aperture formed therein directly opposite the floor aperture, a support chain being attached at a first end thereof to a second chain, said second chain being attached to cargo being restrained in said vehicle, said device comprising: an upper cap attached to a first end of said chain fitting; said upper cap being installed on a top side of the floor with a second end of said chain fitting running through said floor aperture and bracket aperture and through a top side of the bracket; a lower cap attached to said second end of said chain fitting opposite to said first end thereof; said bracket aperture having a greater diameter on a top side than a bottom side to form a rim between said top side and said bottom side of the bracket aperture, a top portion of said upper cap comprising a beveled edge portion that is removably attachable and abutting against said rim; and means for removably attaching said support chain to the second end of said chain fitting; wherein the chain fitting and the support chain are firmly retained to the floor of the vehicle and to prevent removal of the chain fitting from the floor of the vehicle; and wherein at least one portion of the chain fitting is accessible for connecting with the support chain while the at least one portion of the chain fitting is enclosed within an area occupied by the bracket. 2. The device of claim 1 further comprising a chain piece along a section of the chain fitting to provide at least one location to secure the cargo to the chain fitting using a grab hook. 3. The device of claim 1 wherein the means for removably attaching said support chain to the second end of the chain fitting comprises a clamping hook which fits over the support chain and the chain fitting; wherein said upper cap detachably connects with the floor of the vehicle utilizing a handle built-in the upper cap; and wherein the beveled edge portion contacts the top side of the bracket to provide detachability of the upper cap from the floor aperture to allow repositioning or retaining of the chain fitting to secure the cargo. 4. The device of claim 1 wherein said upper cap has a handle formed thereon for use in installing and removing the upper cap from the bracket aperture and the floor aperture; wherein the upper cap attaches to the second end of said chain fitting and receives tension from said chain fitting; and wherein the lower cap tightly fits into the floor aperture to prevent the lower cap being released from the floor aperture when the chain fitting occupies a substantially vertical position.
